What We Like

At first glance, the AT108 doesn’t resemble an entry-level acoustic amp. The construction is top-notch, and it has a ruggedness to it that indicates it’ll survive a beating. It’s exterior is stylishly vintage, and it wouldn’t look out of place in a classy speakeasy.

The sound amplified by the AT108 matches its exterior well. It’s a bright and vibrant tone with that unmistakable vintage character. The VTC technology gives it a warm tone, even though it’s a solid-state amp.

  • Portability makes it easy to take along during practice or on gigs
  • It’s very affordable
  • The VTC adds clarity and warmth to the sound

The effects are also channel-specific so that you can tweak your microphone and instruments separately, for instance. This feature gives you an exceptional level of control that you can use to maximize your sound quality.

The mute switch is also useful, especially when tuning and plugging/unplugging instruments. It helps avoid those annoying “pop” sounds. It’s also helpful in accessing effects on the fly for some fantastic twists on your performance.

The construction itself is rigid and compact, considering the power this thing provides!

  • Onboard effects allow you to fine-tune your output even without a mixer

The battery life on this amp is at around 8 hours (although ours reached a little over 7). A more robust battery would better serve you here, but still, the longevity is impressive. Besides, you have the option of plugging it into an AC power as a standard amp during gigs or at home.

Yamaha THR5 Mini Acoustic Guitar Amplifier – Best for Home and Studio Recording

Yamaha THR5 Mini Acoustic Guitar Amplifier with Cubase AI Production Software

The Yamaha THR5 Mini Acoustic Guitar Amplifier is a portable acoustic guitar amp made for off-stage playing and studio recording.

Key Features

  • Designed for use with electro-acoustic and silent guitars
  • Uses Yamaha’s proprietary sound modeling technology
  • 10-watts powered amp
  • Features 8-cm speakers

What We Like

At first glance, this is a very underpowered (at 10 watts) and slightly overpriced guitar amp. Well, that’s what we thought initially. The THR5 is a compressed combo amp, which features 8 cm speakers. The sound output is surprisingly robust and can efficiently work in smaller volumes. Seems a bit impossible, eh?

The “secret sauce” is in Yamaha’s sound modeling technology. This does an excellent job of replicating the authentic sounds of a tube amp, giving you that warm, rich sound. It also has a slew of onboard effects and voicing modes to add even more realism to your sounds.

That being said, where the THR5 shines is in home or studio recordings. The included USB connection sends that warm tone straight to your computer. The bundled Cubase AI sound software is also a big plus.

What We Didn’t Like

This is an underpowered amp given its price range.


  • Sound modeling and effects give accurate and realistic tone output
  • USB connection and software make it great for direct recording to your computer
  • Small and compact makes it very portable


  • Very underpowered for the price

The Yamaha THR5 is undoubtedly a unique combo guitar amp. If you’re looking to add some realistic tone or unique effects to your guitar recordings, this is a good pick.

Overall Rating: 4.3 / 5

What We Didn’t Like

Marshall AS100D Acoustic Series – Best Heavy-Duty Amp

The Marshall AS100D Acoustic Series is one of the top acoustic guitar amps from the legendary brand.

Key Features

  • 100-watt solid-state amplifier
  • Two 8-inch speakers for stereo output
  • Four channel inputs for multiple instruments and microphones
  • Stereo DI and Line Outs

What We Like

The Marshall AS100D is a beast of an amp. The 100-watt power rating is robust enough to produce loud and clear sounds, but you might argue, there are plenty of other amps with more power than 100.

No, where the AS100D excels is in its features. It features not two but FOUR channels, which is rare for a single amp. You can plug in a host of instruments and microphone inputs here, possibly for a whole ensemble. This gives you plenty of flexibility playing in larger venues.

The sound quality of the AS100D is excellent. The mid-range is pretty comprehensive and bright and can get full with just some minor EQ tweaks. In its raw form, however, the sound can be harsh.

Thankfully, this is another part where the AS100D excels. If offers plenty, and I mean plenty of settings and controls. Each channel has slightly different controls from the others. Everything from gain to EQ, to phase power and contour switches.

What We Didn’t Like

This is a relatively heavy amp, which can make transport difficult. The price is also a bit steep with this one.


  • Multiple channel inputs offer a wide range of versatility
  • 100-watt power blasts crisp and clear audio quality
  • Plenty of controls to help fine-tune your output


  • Quite heavy
  • Pricey

The Marshall AS100D is one of the best acoustic guitar amps you can buy. It’s feature-packed with a host of impressive features. If you’re looking for an all-in-one guitar amp for larger gig venues, this is a serious contender.

Acoustic Guitar Amp Buying Guide

Acoustic Amps vs. Regular Amps: What’s the Difference?

If you’re thinking of buying any regular amp for your acoustic guitar, you’re making a critical mistake. Unlike electric guitar amps, the acoustic variety is all about faithful reproductions of your guitar’s sound. They feature cleaner tones and don’t distort the output like what an electric amp would do. Want to see more guitar options? check out some other top picks here.

Factors to Consider When Buying an Acoustic Amp

Feedback Control

An excellent acoustic amp will have a way to help minimize feedback coming from your acoustic guitar. The fact is that not all acoustic guitar pickups or amplification methods are perfect. Most produce minimal to noticeable feedback. Feedback control is, therefore, an essential feature to help achieve a cleaner tone.

If your amp is over 20 watts, this would usually be standard fare. The most basic is a simple push-button that turns feedback control on or off. While not robust, it’s enough for smaller venues. Higher model amps feature advanced controls and filters that allow you to fine-tune feedback problems.

Where You’ll Use it

Where you are planning on using your amp is probably your most important consideration.

What acoustic amp you’ll get depends on where you plan to play your guitar. Are you just practicing at home, or do you continuously play gigs in large venues? The feature you’ll want to look into here is the watt rating of your amp. This dictates the maximum volume you can amplify.

If you plan to just play in your house, a 20-watt or lesser amp is suitable. For smaller venues like bars or cafes, you can get away with an amp in the 40-100-watt range. Most of these also accept different inputs, like a microphone, perfect for solo gigging.

For those playing in a band, you need somewhere in the area of 100-300 watts. This is because your guitar’s sound will need to compete with the myriad of other instruments in a band setup. A high-powered amp will allow you to amplify your guitar’s music in a loud yet clean way.

If you’re a street or outdoor performer, you’ll have unique needs all to yourself. The challenge is having an amp that’s portable and battery-efficient. At the same time, it needs enough juice to drown out the noise of a busy city street or subway. For decent performance, anything along the lines of 60-watts offers satisfactory quality that’s not much of a power drain.

Onboard Effects

Having the ability to enhance your sound can do wonders for your performance. What you need is generally dependent on the style of playing that you do.

The basics you need to consider are reverb and chorus. Both of these can give you rich, robust sounds that are great for many venues and applications. Some, such as a looping function, is perfect for solo artists who want a background rhythm they can play with.


Multiple channels allow you to plug in many different instruments or sound inputs directly into your amp. The most basic we recommend is a dual-channel input that gives you the option to use your microphone. This basically turns your amp into a PA system and is useful for smaller gigs.

It’s best to get an amp also allow you to control each channel with effects and EQ settings independently.

Final Thoughts

As we’ve seen, you have plenty of choices when it comes to the best acoustic amp, but if we had to pick one off this list, we’d go with the Fishman Loudbox Artist.

This is one of the most feature-packed amps out there. The 120-watt power is more than enough for most venues. The sound output is fantastic and is one of the most accurate out of all amps we’ve reviewed. The various features are all useful additions to any serious musician’s gigging toolbox.

This makes the Loudbox Artist the best acoustic amp that gives excellent value for your money.
